基于PLC在地铁信号灯自动报站系统的设计(任务书,开题报告,外文翻译,论文10000字)
摘要
本随着社会的快速发展，地铁作为新的交通工具，为了提高地铁的服务档次和整体性能，希望能给乘客一个放心，便利，健康，安全的全新的出行方式，地铁也正在积极发展并不断进步。最早的地铁报站全部来自语音提示和乘客通过路线指示图得知要到的站和列车前往的站，然而在嘈杂的地铁环境下，乘客往往错过要到达的站。随着科技的发展，增加了指示灯让乘客更加直观的从视觉上知道下一站要到的站和列车前往的终点站，给乘客带来了很大的便利，除去了乘客因为车内嘈杂而误站的烦恼。
本文中,是采用基于可编程逻辑控制器(PLC)的地铁车站信号灯自动报站系统设计，主要由可编程控制器（PLC）、双色二极管、串行计数器、驱动装置和触摸屏组成。运用双色指示灯模拟进行和蜂鸣器到站和指示灯到站，对所到站进行双色二极管显示，不仅准确解决乘客到站的问题，而且成功地减少了乘客因为列车人多误站太嘈杂而误站事发率。该设计系统采用PLC与信号灯模块的组合，构成的地铁信号灯自动报站系统具有视觉直观，节约内存、体积小、成本低、可靠性高，安装、调试都很方便的特点。

Abstract
  With the rapid development of society, the subway as a new means of transport, in order to improve the service quality of metro and the overall performance, to provide more safe and comfortable for traveler, real-time and efficient. Convenient public transport services are an important part of the subway system. The earliest subway stops all from voice prompt and passengers through the route indicator diagram to station and train to the station, but in a noisy subway environment, passengers often miss to reach the station. Along with the development of science and technology, increased the light is more intuitive to make the passengers from the vision of know the next station to station and the train to the terminus, bring great convenience, passengers to remove the passenger station by mistake because of the in-car noise annoyance.
  This article is designed by using programmable logic controller (PLC) control of the subway signal automatically stops system, mainly composed of programmable controller (PLC), double color diode, a serial of counter, driving devices and touch screen. Using double color indicator simulation and buzzer station and light station, the station for double-color diode display, not only solve the problem of passenger station accurately, and successfully reduced because passenger train more people standing by mistake is too noisy and stand in the error rate. The design system adopts PLC and the combination of light module, composed of the subway signal automatically stops system has intuitive vision, memory saving, small volume, low cost, high reliability, installation and debugging is very convenient.
Key words: PLC; Drive; A serial counter; Double color diode; touch screen
